IMPROVEMENT IN SPRING BED-BTTOMS.

The Schedule referred to in these Letters Patent and making parl: of thesame.

To all whom 'it may concern:

Be it known that we, HOWARD SMITH, of Groveton, in the county of Goosand State of N ew Hampshire, and JAMES POTTER, of Portland in the countyof Cumberland and State of Maine, have invented a new and usefulimproved Spring-Bed; and we hereby declare the following to be a full,clear, and exact description thereof, which will enable others to makeand use our invention, reference being had to the accompanying drawingsforming part of this specification, in which is shown a top view oftheframe of the bed-bottom and details of other parts, as follows:

A. is a view of the inanner of attaching the spring to the under sideofthe slat.

B is an edge` view ofthe same.

O is a view of a modification of A.

Dis an edge view of another method,

E is a view of the means employed to prevent noise and rattling ot' thesprings as they are expanded and contracted.

F shows the spring with its point to enter the cross-bar of the frame.

G H I are views of the mortise in the slats and the sides of the frame.

Our invention relates to certain improvements in attaching thecross-bars to the bed-frame, in attaching the springs to the slats, andin preventing the springs from rattling in spring-beds.

I are the sides ol" the bed-bottom, having the mori tise a to receivethe cross-bars b. These cross-bars b are cut in two ways, first, as seenat H, so as to allow the bar to lit into a and second, as shown at c, soas to pass over the sides I after being pressed into c. This will holdthe cross-bars without pins or bolts, and will admit of the parts beingcasilypnt together and as easily taken to pieces and packed fortransportation.

The points d ot' the springs I enter the holes e of the c1oss-bars,andcan be easily withdrawn when the bed is to bc taken apart.

Te have two methods of connecting the springs with -the slats.

First, as shown at A, where strips of lea-ther are secured to the underside of the slat, and cut soy as to form small loops f, under which theupperI coil oi' the spring F passes, thus securing the said spring andin a measure preventing noise and rattling.

Second, by contining'thc upper coil by metal staples y, as seen at C,with cloth or other soft materials between the spring and the slat, forthe same purpose as in A.

To prevent rattling we apply, still further, looped or cnt strips of(leather It to the coils of the s prings, as seen at E.

Thus a method oi holding together a bed-bottom is employed, by whichnobolts or pins are used, and which admits of ready taking apart andcompactpacking.

Also, the springs are easily applied and removed, and are prevented frommaking noise when the bedbottom is pressed down by the weight of theperson occupying the same. D shows a method where a .ring of metal,having four hooks, is attached to the under side ofthe slat. These hooksclamp the largest ring of the spiral and thus hold it to the slat.Y

We do not claim independent hooks with daring mouths, in combinationwith coiled springs, nor fastening the spring by havingone end of itpierce a bed-slat; these are embraced in the patent of D. I. Webster andH. IV. Ladd, September 10, 1867. Neither do Awe claim the combination oftwo plates, a stud, and a shoulder to hold a spring, nor the same incombination with an additional shoulder. "hese are covered by the patentof. N. .13. White, October 23, 1866. Ours differs from the first-namedof these patents in not employing the hooks to secure the coils of thesprings; and second, in not having the springs so' formedas to piercethe slats at all. fastening the springs -to the slats is whollydii'erent from Whites patent, because we attach strips of leather to theunder side of the slat and make small slits therein, (see f,) which makea sort of loop, and in under the loops the end of the coil is passed, asshown in lig. A, or as in iig. C; the same means employed to fasten theleather to the slat fasten also the largest coil ot' the wire-spring.The point d ot' the spring F does not enter or pierce the slat at all,but enters the hole c on the cross-bar.

What we claim as our invention, and desire to secure by letters patent,is-

A. spring bed-bottom, as herein described, that is, combining the twoparts I I b, the two cross-bars put together `without bolts, and thecoiled springs attached to the slats bymeans of the looped and slittedleather pieces f fastened to the slat, as herein set forth.
